IMPROVEMENT IN VAPOR-BURNERS.

Specication forming part of Letters Patent N0. 164,230, dated June 8, 1875,' application tiled December 16, 1874.

To all whom @t may concern:

Be it known that I, J EREMIAH STEvER, of Bristol, in the county of Hartford and State ot' Connecticut, have invented a new Vapor- Burner; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, side view; Fig. Q, vertical central section.

This invention relates toan improvement in that class of lamp-burners known as vaporburners-that is, a burner which has a-wick within tube closed at its upper end, save slight perfbrations, through which vapor or gas will flow, generated within the tube from the oil or fluid with which the wick is saturated, the burning jets imparting the heat necessaryT for such generation of vapor or gas.

In the usual construction of this class of burners the relative position ot the jets to the wick is unadjustable hence the heat is constant, and more or less light or heat cannot be obtained, if desired.

The object of this invention is to construct a burner so that the burner maybe adjusted relatively to the wick, so that the heat and consequent flow of vapor may be varied at pleasure; and the 'invention consists in the arrangement of a sleeve over the wick-tube, movable freely up and down on the wick-tube, and having the burner attached to the said sleeve, so that by raising or lowering the said sleeve the burner will be accordingly raised from or brought near the wick, to reduce or increase the genera ing heat and consequent ilow of vapor, combined with a packing, in connection with the sleeve, to prevent the escape ot gas between the sleeve andV tube, as hereinafter described.

A is the base, constructed for attachment to or connection with the fount, in the usual manner; B, the wick-tube. Over this wicktube B a sleeve, C, is tted, so as to be movedl freely up and down on said wick-tube.` On the upper end of said sleeve C the burner D is closely fitted, substantially as it usually is, to the wick-tube. The lower end of the sleeve is tted with a cork or other packing, E, to prevent the escape of gas between the tube and sleeve, as also to insure sufficient friction between the two to hold the sleeve at any point of elevation it may be set. The Wick is placed in the tube B in the usual manner, and the sleeve with its burner set over the tube, as shown; then the burner is lighted in the usual manner, too well known to require description.

At any time, and it' for any purpose, it is` desirable to reduce the jets, raise the sleeve and burner, as denoted in broken lines; this carries the burner up from the wick, and consequently reduces the generating heat, and to
